BMW 3 Series E36 E46 Steel Drift Twin Brake Caliper Weld-On Adapter Kit

purpose-built weld-on solution for building a true dual caliper rear brake setup on the E36 and E46 chassis. These high-strength steel mounting brackets allow a second factory rear caliper to be fitted directly to the trailing arm, enabling independent hydraulic circuits for a dedicated drift handbrake setup. Designed for motorsport and track use where a separate hydraulic handbrake circuit is required alongside the standard rear brakes.

Features:

• Constructed from 12mm (0.5") high-strength steel for maximum rigidity and reliability under motorsport conditions
• Allows mounting of an additional factory rear caliper to the trailing arm for a true dual caliper drift setup
• Supports independent hydraulic circuits – hydraulic handbrake can be run separately from the main rear brake system
• Compatible with E36 and E46 rear trailing arms and disc brake suspension arms
• Weld-on fitment for a solid, permanent, and rattle-free installation

Specifications:

• Condition: 100% Brand New
• Type: Dual Brake Caliper Weld-On Adapter Brackets
• Material: High-Strength Steel
• Thickness: 12mm / 0.5"
• Setup: Dual caliper – independent hydraulic circuit compatible

Fitment:

• BMW 3 Series E36 – all rear trailing arms (excluding Compact / 318ti variants)

• Compatible with E36 and E46 calipers and disc brake suspension arms only

Contents:

• 1x Pair of Weld-On Dual Brake Caliper Adapter Brackets

Benefits:

• Enables a dedicated hydraulic handbrake circuit without compromising the main rear brake system
• Ideal for drift builds, circuit use, and motorsport applications requiring independent rear brake control
• Permanent weld-on design eliminates flex and movement under hard braking or handbrake use
• Cost-effective solution to achieve a professional dual caliper setup on the E36 and E46 platform

Installation Notes:

• Weld-on installation – professional welding required for safe and correct fitment
• Removal of the ABS sensor is required prior to installation
• Original caliper from a matching vehicle with the same engine and brake disc size must be used
• Trimming of the brake dust shield will be required to allow correct caliper clearance
• Not compatible with E36 Compact or E46 Compact (318ti) models
• If unsure about compatibility, contact our team with your chassis code and brake disc size before ordering

Warranty:

• 12-month standard warranty from date of purchase
• Contact our support team for assistance with any issues
